OSCILLATING GRAVITY-MOTOR.

,SPECFICATIN forming part of Letters Patent N o. 620,032, dated February21, 1899. Application tiled July 6, 1897. Serial No. 643,657. (Nomodel.)

T all whom t may concern:

Be it known that I, WILLIAM LEVANT HAR- VEY, a citizen of the UnitedStates, residing at Gosford, in the county of Armstrong and State ofPennsylvania, have invented certain new and useful Improvements inOscillating Gravity Motors or-Engines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the accompanying drawings,

which form a part of this specification, in which- Figure 1 indicates aside elevation of my improved oscillating gravity-engine. Fig. 2 is aplan view of the same. Fig. 3 is an end view of the same.

My invention relates to mechanical motors; and my object is to produce adevice which, with the expenditure of a comparatively small power, alargely-augmented force or power is generated, and to this purposeconsists, primarily, in the use of two heavily-weightedoppositely-oscillating levers fulcrumed upon a reciprocating inclineplane, combined and arranged as hereinafter more specifically set forth,reference being had to the accompanying drawings, forming part hereof,in which like letters and numerals indicate similar parts Wherever theyoccur.

Referring to said drawings, 1 and 2 are respectivelylevers, beams, orpendulums, the

lower ends of which are provided with heavy.

Weights b and are pivotally fulcrumed upon arms or pitmen 3 3, adaptedto be reciprocated up and down the incline planes 4 4, which aresuitably secured to the frame of said machine over antifriction-rollers5 5, secured in said incline plane by the oscillation of said levers.The upper ends of said levers, on both sides of the same, are providedwith impact-blocks 6 6, the outer edges of which are curved, as shown,which, engaging upon and operating over the roller 7, secured in theouter ends of the brackets 8 3, secured to the frame of said machine,serve to reciprocate said pitmen 3 3 by the oscillation of said levers..The outer or upper ends of said pitmen terminate in a clevis or yokepivotally connected at c to the lever 9, which is mounted upon the shaft10, journaled in bearings in the standard 11, which is bolted orotherwise suitably secured to the bed-plate of the machine. The upperends of said levers are connected by a plate 12, and upon the innersides of the same are pivotall y secured pawls 13 13, adapted to meshwith the teeth arranged upon the upper edges of the large gear-wheel 14,mounted on the shaft 10, whereby the said wheel is rotated by saidpitmen on their downward stroke, as hereinafter specified, said pawlsbeing held in engagement with teeth on said wheels by the outwardpressure of the springs 15 15, and being adapted to trip over said teethon the upward stroke of said pitmen, as hereinafter specified. Saidwheels 14 14 are also provided with teeth in the periphery thereof,which mesh with and communicate power to spurwheels 16 16, mounted,respectively, upon the shafts 17 and 13, which are suitably secured inbearings 19 and 20, secured to the bed-plate of said machine. Powercommunicated to said shafts 17 and 18 is transmitted through thesprocket-wheels 21 and 22, mounted on said shafts, respectively, to thesprocketwheels 23 and 24, mounted on the shaft 25 by means of the chainsor other suitable gearing 26, and thence to the fly-wheel 27, mounted onsaid shaft 25. A drum or belt pulley 28 is also mounted on saidlast-mentioned shaft 25 for the purpose of transmitting power to thedynamo 29 by means of the belt 30. Electrical current generated by saiddynamo is conveyed through suitable conductors 31 and 32 to the electricmotor 33. A shaft 34, operated by said motor, is provided with a cog 35,which meshes with and transmits power to a larger cog-wheel 36, mountedupon the shaft 37. Said cog 36 is of considerable width, one half of theperiphery of the same having the teeth removed, the cogs on the otherhalf of the periphery being adapted to engage the teeth on the rack 38,whereby said rack is caused to move in one direction until the continuedrevolution of said cog 36 presents the cut-out portion thereof,which,releasing said rack, enables the oscillating levers, connected to theouter end of said rack by means of the rods 39 39, to move orreciprocate said rack in an opposite direction until the continuedrevolution of the cog again meshes therewith,whereby said levers, inconjunction with its own momentum, are oscillated backward and forward,a much less percentage of the power generated by said oscillating leversbeing required to keep the same in motion when started.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In a mechanical motor or engine,the combination of twooppositely-oscillating levers, the lower ends of which are heavilyweighted; pitmen connected to the upper ends of said levers; an inclineplane upon which said pitmen are adapted to reciprocate;upwardlyprojecting levers; means to connect said pitmen and said levers,and suitable gearing adapted to be connected to said levers,substantially as set forth.

2. In a mechanical motor or engine,the combination of twooppositely-oscillating levers, the lower ends of which are heavilyweighted; pitmen connected to said levers near the upper ends thereof,incline planes upon which said pitmen are adapted to reciprocate by theoscillation of said levers; upwardly-projecting levers mounted on ashaft and adapted to be connected with the upper ends of said pitmen;gear-wheels having teeth arranged upon both sides the rim thereof,adapted to be engaged by pawls carried by said upwardly-projectinglevers, and suitable mechanism connecting said gear-wheels with a dynamoand motor, substantially as set forth.

3. In a mechanical engine or m0tor,the combination of twooppositely-oscillating levers, the lower ends of which are provided withheavy Weights and the upper ends with impact-blocks; rollers suitablysecured in the frame of said machine; pitmen connected to said leversnear the upper ends thereof; ineline planes upon which said pitmen areadapted to reciprocate; upwardly-projecting levers mounted on a shaftand connected to the outer end of said pitmen; gear-Wheels mounted onthe same shaft as said upwardlyprojecting levers and adapted to meshwith pawls carried by said levers; means to communicate power to saidgear-wheels to a dynamo and motor; a rack adapted to be driven by saidmotor and connected to said oscillating levers near the lower endthereof, substantially as described.

In testimony that I claim the foregoing I hereunto affix my signaturethis 24th day of April, A. D. 1897.
